What is the primary use of the HHD on board?

• A. Navigate the flight path
• B. Monitor cabin temperature
• C. Manage passenger seating
• D. Process credit card transactions for onboard purchases

Answer: (D)

The main idea is that the handheld device used by cabin crew is a portable point-of-sale tool designed to handle onboard sales. It lets crew quickly enter orders, scan items, accept credit or debit card payments, issue receipts, and sync transactions with the onboard revenue system. This streamlines service, reduces cash handling, and keeps sales data accurate in real time. Tasks like navigating the flight path are controlled by the flight deck’s navigation systems, cabin temperature is managed by the aircraft’s environmental controls, and passenger seating is arranged through separate crew apps and seat maps. So, processing credit card transactions for onboard purchases is the primary use.
